摘　　要：利用生物流化床对生活污水的处理进行了试验研究,探讨了生物膜的形成,水力停留时间和供气量对处理效果的影响。结果表明,填料挂膜容易,气水比为15:1,水力停留时间为3h时,进水COD、NH3-N和TN分别为310～550mg/L、30～40 mg/L和35～50mg/L时,其平均去除率分别为90.6%、86.7%和65.2%。The treatment of domestic sewage using the biofluidized bed reactor was studied. The formation of biofilm and effects of hydraulic retention time and volumetric gas rate on efficiency of wastewater treatment were studied. It was easy to formation of the bio-film. The results showed that the average COD, NH3-N and TN removal rate were 90.6%,86.7% and 65.2% respectively under the conditions of air/ wastewater ratio 15：1 , HRT 3 h and the influent COD, NH3-N and TN concentration of 310-550mg/L, 30-40 mg/L and 35-50mg/L.
